I recently bought an older, cinema version, of the 50mm lens, the Rokinon 50mm T1.5, which is also a very good lens.
I’ve had a chance to use the 50mm T1.5 on tests for my upcoming Sony a7RII review. The lens looks sharp and is very fast. It is also clean, with no vignetting on the edges. So I expect these new updated lenses to be even better than the 50mm T1.5 I’ve tested.
All these lenses are great for filmmaking since they have manual focus, which is very important in video production. Also, the focus ring has a long throw – unlike AF lenses – so it’s much easier to manually hit the right focus spot.
I also own older Rokinon lenses, such as the 35mm T1.5 and the 14mm f/2.8. I’ve been very happy with all of them. I’ve used them on the biggest feature film projects I’ve worked on. Although not cheap, I think these Rokinon lenses offer a good value.
